Our client is a company who manufactures pumps and pumping systems.

 


Tested product

Circulator pump

The circulator pump is placed on a heating circuit to circulate water.


 

Boiler circulator

Objective

Our client wants to know how well his product range holds pressure and wants a test bench that can run 3 types of tests:

  • Crash test (product’s breakage)
  • Pressure holding
  • Leak test after customer return

Problematic issues

Creating a test bench that can run pressure resistance tests on boiler circulators and hydraulic units. It was important to be very cautious about safety.

 

Solution and result

The testing area is within a frame where the sink is placed. It retrieves liquid runoff. The tested sample is joined to the centre of the sink.

The pump housing to be tested is installed in a closed circuit. To generate a pressure build-up, a plunger piston goes into the circuit to reduce the volume and increase pressure level via a locking on a pressure sensor.
The circulator pump is tested up to breakage, consequently the bench is not powered by electricity.

To ensure operator’s safety in case of product breakage, the testing area is equipped with crankcases and polycarbonate doors. A safety pressure switch prevents the pressure from going further than 3.5 bar when the doors are open. The doors are automatically locked when closed. An emergency button and a watchdog function make it possible to immediately stop the bench if necessary.

Pressure data measured while running the tests are saved and can be used with software like Excel.

The pressure holding test bench characterizes products and detects its weaknesses. Our client can now improve its products’ quality thanks to the tests results.
